12611261Once the Keychain is writable again, Claude Code moves the credentials back the next time it writes a credential. To force it now, run `/logout` and then `/login`. Logging out removes all stored credentials, including the plaintext file's contents, saved MCP server logins, and plugin sensitive values, so expect to re-authorize MCP servers and re-enter plugin secrets afterwards. Logging in again stores your login in the Keychain.

1263#### Login fails on a network home directory
1264 
1265When a request fails with `API Error: 401` and your [configuration directory](https://code.claude.com/docs/en/claude-directory.md) is on a network filesystem, check whether that filesystem or your quota on it is full. With no room left, Claude Code can't save a new or renewed login to the plaintext [`.credentials.json` file](https://code.claude.com/docs/en/authentication#credential-management), and `claude auth login` can still print `Login successful.`
1266 
1267**1. Make room on the filesystem**
1268 
1269Delete files you no longer need on the filesystem that holds `~/.claude`, or the directory you set in [`CLAUDE_CONFIG_DIR`](https://code.claude.com/docs/en/env-vars).
1270 
1271**2. Sign in again**
1272 
1273Run `/login` at the Claude Code prompt or `claude auth login` in your shell.
1274 
1275Before v2.1.318, when Claude Code saved the login file on a full network filesystem, it could replace a still-valid stored login with an empty file. Later commands then reported `Not logged in`.

12631277### Bedrock, Agent Platform, or Foundry credentials not loading
12641278 
12651279If you configured Claude Code to use a cloud provider and see `Could not load credentials from any providers` on Amazon Bedrock, `Could not load the default credentials` on Google Cloud's Agent Platform, or `ChainedTokenCredential authentication failed` on Microsoft Foundry, your cloud provider CLI is likely not authenticated in the current shell.
